Who it is for
Where the data comes from
Everything here is built from our own crawler and our own index. The graph covers 181,132,097 domains and 2,774,625,913 domain-to-domain links, which adds up to about 798.5 billion backlinks. It is rebuilt roughly monthly.
That cadence matters. A link you built on Monday will not show tomorrow, so use the viewer to watch trends and to audit, and use a manual page check to confirm a single fresh placement. Pairs well with the error cheat table when a call misbehaves.
Who runs this? A small team that likes shell prompts. Details are on the about page, and the formal bits sit under terms and privacy.
